it didn't lag for me the first few times, then it did, and I suddenly understood you ppl's frustrations... the controls are sped up?? cuz as it autoaccs, a slight touch does more and more movements
the badges are all easy. for meadow. you set barrels like crazy, just make sure they are aweay from you, for defense, everytime you get turret gun/mortor, run to a spot you think is good(preferably close to hills or things devils can't attack) then run out and minigun the enemies to hell(rockets suck in this sequel)
